The percentage of dissolved salt in saltwater
is 3.5%.  We are given the amount seawater sample. We would just multiply the two values together.

750 g (0.035) = 26.25 g NaCl

26.25 g NaCl ( 1 mol / 59.44 g ) ( 1 mol Na / 1 mol NaCl ) ( 22.99 g / 1 mol ) = 10.15 g Na

Hope this answers the question. Have a nice day.

its 229.5, which would be C.
